No new changes were required between the 4.16 version of the plugin and 4.17, so we anticipate that the submission process will go pretty fast. One thing to note that is different in 4.17 is the location of the Combine Meshes checkbox:

Changes to the PlayUp Tools Importer for Unreal Engine have been submitted to make it compatible with UE 4.15 and are awaiting approval. When the plugin becomes available for UE 4.15, please note that you will need to ensure the following flag for Combine Meshes is checked for the level import process to work properly.

The PlayUp Tools importer for Unreal Engine 4.14 has been submitted to the marketplace for review. As there were no needed changes to the importer itself, we expect it will be available on the UE Marketplace shortly.

IMPORTANT NOTE: There was one change in UE 4.14 that does affect PlayUp Tools users. In UE 4.14, they have added a flag which allows UE 4.14 to convert the scaling of the FBX files to UE4 units. This converter is on by default, and needs to be turned off as PlayUp Tools already does the conversion process for you.
